Application fi1ed. August 1, 1921. Serial N0. 488,844.

The invention l1as-for an object 10 efl'eot improven1ents in valves useful especially for incorporation upon exhaust conduits of internal con1bust1on eng1nes 111 advance o1. mufliers, wl1ereby 1t n1ay be nsed 111 tesinng engines and otl1erwise as cnsto1nary. It is aparticular ain1 to provido a device 01 t-l1is kind l1aving special advantages :f0r use 111 testing motorcycle n1otors.

Additional objects, advantages and features of invention reside in tl1e con1bination, arrangement and construction of parts, as 1nay be readily understoocl fron1 tl1e descripti0n l1ereinafter and fro1n the drawings, in whioh,

F igure 1 is a side elevational view 01 21 device construoted in accordance with my invention, und inoorporated upon a motorcycle.

Fig. 2 is a cr0ss sectional view 011 tl1e line 22 of Fig. 1..

Fig. 3 is a vertical sectional view 011 the line 3-3 of Fig. l.

Fig. 4 is an edge view of the valve elen1ent detacl1ed.

' F ig. 5 is a longitudinal section o-f tl1e valve.

Fig. 6 is a view of tl1e 'operating pedal.

There is illustrated a valve casing l0conneoted to the front cylinder exhaust pipe 11 and tl1e rear cylinder exl1aust pipe 12 of an internal comb-ustion engine, und arranged nonnally to deliver gases passing theretl1rougl1 to a n1ufiler 13 through a nipple 14.

The casing 10 in its upper and intern1ediate portions is spl1erical in f01111 and hollow, and forn1ed with a cylindrical seat face 15, the medial plane 01 wl1ich is horizontal and dia1netrical. Above tl1e plane 01 the seat 15, the oasing 10 is formed with a horizontal cylindrical rearward outlet enlargen1ent 16, interiorly threaded to properly receive the nipple through whicl1 gases 1nay pass to tl1e mufller, and this may' comprise tl1e sup;porting means for tl1e device, alone,

or in conjunction with tl1e engagement Of one 0.1 botl1 tl1e p1pes 11 and 12 111 tl1e cas1ng. A forward enlargement 17 s1nnlar to and in align1nent with tl1e one 16 is forn1ed 011 the case 10, receiving the pip'e 11, wl1ile a sin1ilar enlargement and projection 18 receiving tl1epipe 12 is forn1ed at the top 01 tl1e casing, inclined forwardly with its axis at an acute angle to the a-xis -of tl1e enlargen1ent 17. O11 a level with then1edial plane o1? tl1e seat 15, a horizontal shaft 19 is mounted in tl1e casing, at rigl1t anglesto tl1e direetion oftl1e enlargements 16 und 17, this sl1aft l1aving a butte1vfly valve 201nounted tl1ereon, eaol1 o1? 1 l1e wings beingollset (so lie in parallel planes spaced onopposite sides 0f tl1e axisv 01 tl1e valve sha1t. When in normal cl osled position, tl1e rear- Wing 21 i s uppern1ost. Tl1e wingsare so shaped tl1at when in horizontal position tl1ey fit snugly against the face of theseat 15, and it Will b e a'ppreciated tl1at tendency of tl1e valve to rotate eounter-cloekwise, as viewed in Fig, 1, Will cause tl1e edges 01 the wings to bear against the valve seat, ar'1d tend to wedge therein, although tl1e angle o1 ineidence in the engage1nent of tl1e\valve With its seat is such tl1at actua l wedging will not occur, but a snug closure of' the valve be' assured at all tin1es wl1en it pressed into e11gaging position, The haft 19 projeots from one side 013 tl1e casing, bhe right l1and side in the present instancewl1ich i.s also tl1e outer side with respect to usual n1otorsarm 26 projeoting vertioally upward when the valve is in closeol position, tl1e other arn1 27 extending rearwardly and slightly down ward, as sl1own. The lever 1s 1or1ned w1th a l1ub port1on 28 at tl1e 1nner s1de, 111 wlnch a springpressed plunger 29 is mounted, paral lel to the axis of the shaft 19 and projected tl1rough tl1e inner side of the hub 28 toward the casing 10. The casing- 10 is provided plunger may be so forn1ed that the pluhger Will ride out of a recess when suflicient force is exertecl upon either 0if the levers. lt 1nay be f0und desirable t0 provicle a raisecl shoulder 31 beside the lowermost recess in ehe boss 30 in the clirection of opening mo-ve- 1nent 0f tl1e valve, so that lt Will not tencl 130 pass beyoncl maximun1 open osition.

The extremities of the arrns 26 and 27 a1"e spurrecl as at 32 whereby pressure 0f the sole 01": the shoe 0f tl1e operator thereon Will be sulficient 130 enable proper movement of the lever ancl actuation 0f the valve as cle sirecl.

t is "CO be noted thai; the lower Wall of the casing is extendecl downwardly nt the forwarcl sicle a greater distance than at the rear side, und is sln1pecl as to f0rn1 a circular opening 34 Wl1ich in -eonjunction with the spherical sha pe 0f 'tl1e casing, has

an effect 0f givlng very clistinct s'0unding '0f tl1e separateexplos1ons 0f the engn1e mth Wl1ich lt may be asso'ciatecl. The saut 15 at the forwarcl sicle, is also Set inwarclly a distance fro1n the Wall 33 so that as soon as the lower Wing 22 of the valve passes below the seat, exl1aust at tl1is side 0f the valve Will begin. It Will also be noted filmt When the valve is in full open osition, tl1e exhaust fron1 tl1e front cylincler pipe 11 Will tencl t0 be warded downwarclly through the deeper forwarcl side 0f ehe casing by tl1e valve itself, und as the 1ear edge ol the ope1v ing 34 is very close t0 the valve seat 15, the1e Will be a clhference in the souncl of e xl1aust f1 0n1 tl1e front and 1ezu cylinclers in the ca'se 015 a two cylinder engine connected as desc'ribed, reacllly enabling th e detection 0f' faulty explosion in either cylincler.

The device has especial advantage i01 900- nOn1ical nmnufacture, ease of installation ancl com'pactness, as well as readiness 0f Op eration by the foot 0f a 1notor cyclist.

A forwarcl pres5ure of the foot when lested upon the zirn1 26 as clo'tted in Fig. 1 Will xnove the v-alve toward open position, und as the arm 26 mc ves past a po'sition where lt could be reaclily returned t0 closecl osition by the foot otf the operator, khe sec 011d arm 27 comes into position whe1e lt ca'n easily be operated f01 that purpose. Tl1is Will obviate tl1e necessity f01 a cyclist dismounting while 011 Ehe load when desir- 0us of operating a testing valve t0 l1ear 11101e clearly the= souncl 0f the exhaust.

113 1nay be desirable f0r solne forms of 1110- t0rs t0 arrange the axis 0f the shaft 19 in a different relation t0 the conduits leacling into tl1e casing, vvl1ich may be clone as found requisite.

In Fig. 5 I have shown a stop lug formed integrally With tl1e valve casing, located upon the interior, f01 checking open- 'i1'1g n1ove1nent 0f the valve 22. In the event (hat Ehe lug 35 is employecl in tl1e vulve, it Will, 0f course, be understood that t110 checking device 31 is eli1ninatecl.

lt l1as been founcl, in P1actic@ that in 0ertain types 0f 1nachines, the kick starter edal interferes witl1 the opening und closing 0f l:l1e valve, With the operating levers 26 und. 27, tf01n1ecl as shown in Fig. 1. Hmvever, by "1'01111i11g the levers at an mute angle t0 each'other, as indicated in Fig. 6, operation 0l": the kick starter may be accomplished with the valve in either open 01 closecl position, without interference.

l. A. 1notor testing valve comprising u cas-- ing huving 'tw0 inlets und 21 normal 0utlet, und havin'g aauxillary outlet port 0f l2uge 2-.1ea, a valve 1'50 close tl1e auxilia1y port rnovable witlzin the ca.sing t0 21 position iniermediately of the inlets, whereby dillerence 0'f di rection in tl1e souncls 0'f exlmust fron1 the tw0 inlets Will be procl'ucecl.

2. A 1no'tor testing valve comprisingucasing 1aving two inlets and a normal 0utlet l01 -a 1nuffl@r connection, be inlets bsing directed towarcl the outlet, an exl1aust port in the c-ase lraving a sent, a 'valve thevefor movable t0 interpose when 0pen a substantial p-a1t between tl1e paths 0f gase's entering the inlets, whereby clifference in the souncl 0l disclnuge fl'0111 tl1e two inlets Will be prodnced thereby.
